The biggest mistake most people make in crypto is trusting people. I know a lot of investors who have lost a lot of money because of their naivety.
Wait a minute, what do you mean by trusting other people here?
Did you give your private key to someone else? or entrust your money to that person without knowing clearly who and how that person is?
I am one of those who trust other people, in this case a friend who tells me everything about crypto. even my friend taught me about how to invest there. Before I was on this forum, I once entrusted my money to invest in crypto even though I didn't know what crypto was. but only with this trusted capital, my friend was able to manage it well and was very transparent, even when his investment experienced a decline, I was always informed.
